RAIL-CLAMP.

Specification of Letters Patent. Patented'July 22, 1919.

. Application iled April 24, 1919. Serial No. 292,414.

The object of the invention is to provide a clamp which will adjustitself to variations, inequalities and irregularities in either the railbase flange or the supporting vcross tie or other member to which therail is to be secured. v

. base ange.

In the accompanying drawing Figure l is a transverse section through arail and the clamp engaging the same; and Fig. 2 is a plan view of theclamp.

In the drawing l indicates a railroad rail of standard design having theusual base flanges 2. 3 indicates the base member to which the rail issecured, and which may be a metallic cross tie, a girder or stringer ofany kind, or a concrete base or foundation member. l indicates the railclamp, the same having a body ofthe necessary dimensions and provided atone side with a projecting lip 5 which extends over the rail base flangeand has its lower face shaped to conform to the upper Vface of the railThe body of the clamp is provided with a hole 6 for receivingthefastening bolt 10, which will extend through or be anchored in thefoundation or base supporting member" 8; This hole 6 is slightlyelongated in a direction normal to the axis of the rail, as shown inlFig. 2, thereby allowing for the adjustment of the clamp toward andfrom the rail in order to accommodate itself to variations in thicknessor width of the rail base flange, or in the positionof the rail relativeto an anchored Copies of this patent 'may be obtained for fixed bolt,and nevertheless permit the clamp ing lip 5 to properly seat on the railbase flange. `This hole is furthermore flared, that is, increased insize from the central portion of the body both upwardly and downwardly,in order that the clamp may adjust itself by tilting either lengthwisearound the end angle 9, or sidewise, to accommodate itself'toirregularities in either` the rail base flange, or in the cross tie orother foundation member. This hole is flared in a manner to bring thewall portion 7 thereof parallel to the wall portion 7a and the wallportion 8 parallel to the wall portion 8a, as a result of which theclamp can tilt slightly in any direction, even though the bolt fill thehole fairly well.

This clamp will be made in several standard sizes to accommodate railsof various weights. It will preferably be made by a forging operation,in suitable dies shaped to give the iinal form to the clamp, the diesbeing provided with projecting portions to form the hole 6. f

I claim:

1. A rail clamp having a body provided with a lip to extend over therail base flange and provided with a bolt hole which increases in sizefrom approximately the vertical middle of the body toward both the topand bottom faces thereof.

2. A rail clamp having a body provided with a lip to extend over therail base flange and provided withV a bolt hole which is elongated in adirection normal to the rail to be clamped and increases in size fromapproximately the vertical middle portion of the body toward both thetop and bottom faces thereof.

In testimony whereof I have hereunto set my hand.
